Application filed October 12, 1904;. Serial No. 228,106. I

To all whom it may concern:

Be it known that I, CLARA B. MILLER, a citizen of the United States,residing at Sewaren, in the county of Middlesex and State of New Jersey,have invented certain new and useful Im rovements in Dish-WashingApparatus, 0 which the following is a specification, such as will enablethose skilled in the art to which it appertains to make and use thesame.

This invention relates to dish-washing a paratus, and the object thereofis to provi e an improvedapparatus of this class which may beconveniently used in hotels, restau rants, and other places of thisclass, as well as in dwellings or for family use, a further object beinto provide a dish-washing apparatus whic is simple-in construction andoperation and comparatively inex ensive and by means of which all kindsand c asses of dishes of any shape or form, together with pitchers,goblets, cups, glasses, and other hollow vessels,

and also knives and forks may be quickly,

easily, conveniently, and thoroughly washed;

and with these and other objects in view the invention consists of an aparatus of the class s ecified constructed as liereinafter deand claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate artsof my improvement are designated by suitable reference characters ineach of the views, and in which I Figure 1 is a sectional elevation ofan apparatus involvin my invention, and Fig. 2 a section on the ine 2 2of Fig. 1. I

In the practice of my invention I provide a tub a, which may be composedof any desired material and WlllCll, as shown in the drawings, is oblongin form, but which may be of any desired shape in cross-section. Thesides and ends of the tub a are inclined downwardly and inwardly in theform of construction shown, and in the bottom of the said tub andcentrally thereof is a longitudinal trough 11 formed by a false bottom(L in one end of which is a strainer a, and a draw-ofi or escapewater-pipe a communicates with one end of the trough o The tub or isprovided in the formof construction shown at two different points withinwardly directed supports 6 and b, which extend around the $1 es andends thereof, the bottom support I) being at a predetermined distanceabove the bottom of.

the tub and-the top portion 6 being preferabl about half-way between thesupport I) an the top of said tub, and placed on the support I) is atray 0, composed of open wirewor and another tray 0 is placed on the suport b and also com osed of open wirewor and the trays c an 0 areprovided with handles 0 by which they may be removed from the tub a andplaced therein whenever desired.

I Adjacent to the tub a is placed a forcepum d, with which is connectedthe pipe d whic is in communication with a tank (1 which is providedwith a water-supply pi e d, and a gas-burner d is placed under t e tank(1 for heating the same, and gas is supplied to said burner by a pipe d:The tank d may be heated, however, in any desired manner, and said tankis provided at one end with a thermometer d, by which the temperature ofthe water therein may be determined. Connected with the pump 1) is awater-lead pipe e, which extends into the bottom portion of the tub a inthe form of construction shown and through the trough a to about themiddle thereof, where it passes u wardly through the false bottom a ofthe tu a, as shown at c and connected therewith within the space betweenthe support I) and the false bottom a is a rotary water-sprayer 0?,having arms a, three of which are shown and the ends of which are allcurved in the same direction,

and these arms are finely perforated on their upper sides, as shown inFig. 2.

In the top portion of the tub a is placed a water-sprayer tube f, withwhich is connected a pipe f which extends from-the pipe 0 within the tuba up to and communicates with the water-sprayer tube 7, and saidwater-sprayer tube f is perforated on its bottom and inner sides, so asto throw water entirely over the tray 0 while the perforationsin thearms 6 of the sprayer e are so formed as to enable the said sprayer tothrow Water over the entire bottom portion of the tray 0 and on and overthe contents of said tray. The upper tray 0 is'intended for holdingdishes or similar shallow articles, and the bottom of said tray isprovided with transverse raised portions g, forming in the interior ofsaid tray corresponding transverse depressed portions g an the to ofsaid tray is provided with transverse ro s 9 which correspond with thetransverse raised portions 9 and are'directly over the opposite sidesthereof, and in placing dishes, pie-pans, and other shallow articles inthe tray 0 the said articles are inserted into IIO the tray between thetransverse rods g into the transverse depressed portions g at the 7 tomtray 0, as hereinbefore stated, is intended to receive pitchers, cups,glasses, goblets, and other hollow articles of this class, and saidarticles are placed in said tray with the bottoms up, the open ends ormouths thereof being directed downwardly, and in the operation of, theapparatus the dishesor other articles having been placed in the trays cand c and said trays havin been placed in the tub a the cover a of saitub is placed in position and a uantit of boiling water is turned ontothe dis es in t e said trays, a teaspoonful, orthereabout,of-powderedsoap having been first dropped into the tub The appara-. tusis then manipulated, so that the water will pass only to the bottomsprayer e, this operation being-acomplished by means of a valve h in theu per 'end portion of the ipe f. The pump 5 is then operatedfor a outtwo minutes, at the end of which time the valve his opened, and thewater has access to the bottom sprayer e and the top sprayer f. The pump(1 1s then operated for two or three minutes, at the end of which timethe water is allowed to run off throu h the which is provided with a vave 1 cover a is lifted and the water in the tub allowed to drain OE, andthe heat will be sufficient to dry the various articles in saidtr'ays inafew minutes, and the said articles may also be wiped in the usualmanner, if desire and may then be put. away for use." The tank (1 isalso provided with a removable cover 9', and said tank may be located atany desired'point, and the p pe d which com.

municates therewith, is provided with a valve 7'. The rotatable sprayere is preferably mounted on ball-bearings, which are not'shown; but themounting of this sprayer or its connection with the pipe 6 maybe madel'nanydesired manner, the only object in this connection being to somount the saids rayer that it be caused to rotate freely by the force ofthe water flowing out of thecurved ends of the arms 0* thereof.

My invention is in no way limited to the exact construction of the traysc and c, all

that is necessary in this connection being that} the said trayscomposedof open wire-Work, I

Having fully the space beneath sai pi quan tity of boiling Water is thenpoured into the tub over the trays and the contents thereof, 1 as at thebeginning, and the pump is again 0 erated for a minute or more, afterwhich t -e pressure to said spraying. device, substanso' as to permitthe water to flow freely therethrough or. through all parts thereof,another object being to so form the upper tray that dishes or flat orshallow pans or similar arti cles, such as pie-pans or the like, may beplaced therein or supported therein .on edge or in an-inclined positionin order that the water from the sprayer f may be thrown over all artsthereof.

his apparatus is simple in construction and operation. and comparativelyinexpensive and may be used wherever apparatus of this class isrequired, and changes in and modifications of the construction hereindescribed may be made without departing from the spirit of my inventionor sacrificing its advantages.

described my invention, What I claim as new,-and desire to secure byLetters Patent, is-
